What is Chalcosis oculi?

Chalcosis oculi (Greek chalkos: copper): Chronic ophthalmic exposure to particulate elemental copper or one of its alloys may result in its deposition in the cornea, lens, vitreous and retina. Copper deposits in the cornea (chalcosis corneae) appear as golden brown, ruby red or green pigment ring in the peripheral Descemet's membrane (Kayser Fleischer ring). Lens opacities (chalcosis lentis) occur in the form of anterior subcapsular cataract ('sunflower' cataract and typically greenish in color).
